Rhino trial version expired after less than 30 days

After an windows 10 update, the trial is not working anymore.
What can i do?

Hi Greg,

Did the system time and date get messed up with the upgrade? This would cause the eval to expire. Please email Sales@McNeel.com if the system time and date is right and the eval has been installed for less than 90 days.

Hi Brian,
I realised that I never thanked you for your help.
I contacted Mc Neel and they fixed it.
Thank you!
